Using datablocks and different models

Hi,

I've been trying to figure out how to make my NPCs have different models from the player and from each other. I'm using the Orc from realm wars as the player model and want to use the space orc for various NPCs for now. I can get the player and all NPCs using either one of the two models, but can't seem to figure out how to get them all to use different models from each other.

I've tried creating a different datablock and setting the model in that. I wanted to inherit from lightmalehumanarmor so that I would have all the standard stuff that is in that datablock. So what I did was this

datablock PlayerData(OrcMaleHumanArmor : lightmalehumanarmor)
{
classname = "Armor";
shapeFile = "~/data/shapes/spaceOrc/player.dts";
debrisShapeName = "~/data/shapes/spaceOrc/debris_player.dts";

};

I'm apllying it to my NPC in the mission file as follows

new AIPlayer(Bob) {
position = "1121.2 451.103 259.86";
rotation = "1 0 0 0";
scale = "1 1 1";
dataBlock = "OrcMaleHumanArmor";
enemy = "1";
};

At first it kept giving me the following errors
Object 'OrcMaleHumanArmor' is not a member of the 'GameBaseData' data block class
game1/data/missions/atlas.mis (0): Register object failed for object Bob of class AIPlayer.

And of course my NPC failed to appear. I thought maybe it was because the cs file with the datablock wasn't being exec'ed early enough in the load so I moved it up above the point where the error was ocurring. That got rid of the error, but now the game gets as far as "Engine initialised" and just hangs with no errors.

I've also tried leaving the datablock as LightMaleHumanArmor and just overriding the shape and debris_shape params when I "new" my NPCs, but that doesn't work either. The NPCs just end up with the player model

If anyone can explain or point me at a resource that shows how to give different characters different models and/or datablocks I would be very grateful.

Thanks a lot,

Dave.
